Dear Avril,
                Thank you for the striking image that your post inspired. That 
                is, the thought of Noah's Ark including living examples of every 
                species of freshwater and terrrestrial mollusk (presumably leaving 
                the marine ones to fend for themselves). This collection, which 
                would have been far superior to any reference collection of these 
                animals existing in the world today, could only have been gathered 
                together by someone with an uncanny eye for minute specific distinctions 
                among these variable creatures, so Noah must have been the greatest 
                malacologist of all time as well as the greatest collector. What 
                a pity that Noah had to disperse his collection, eh?
                
                While we are on the subject of traditional stories, let me recommend 
                a couple of books by Adrienne Mayor:
                Fossil Legends of the First Americans.
                The First Fossil Hunters: Paleontology in Greek and Roman Times.
                
                In these books, Mayor shows that people were aware of the existence 
                of fossils well before the advent of modern science. Some of the 
                evidence is archaeological, including fossil collections recovered 
                from an Egyptian temple and a Roman palace on Capri, and a Greek 
                vase showing a fossil skull in a mythological context. Other evidence 
                is historical or literary. In some cases, she attempts to trace 
                legends to fossil inspirations, for example, the one-eyed, giant 
                Cyclops was supposed to live in an area known for its fossil elephant 
                remains, and elephant skulls do look as though they have a single 
                large eye socket in front. (It's a trunk socket. The real eye 
                sockets are smaller and on the sides.) In another example, the 
                legendary griffin may have been inspired by fossils of Protoceratops 
                in the Gobi Desert. This one is a bit of a stretch, but the sheer 
                weight of detail in Mayor's book shows beyond a doubt that the 
                ancients realized that fossils were the remains of once-living 
                organisms, and were curious about them. They didn't have all the 
                answers but they did have good questions.
                
                Cheers,
                Andy
